The PyroCouple series are compact, high-quality, low-cost sensors that measure the temperature of inaccessible or moving objects or materials. They measure temperatures from -20 ° C to 500 ° C, precisely and consistently, with an outstanding response time of 240 ms.
PyroCouple sensors are available in two-wire or four-wire units.

The four-wire sensors transmit the target temperature as an output of 0 ~ 50 mV or thermocouple (type J, K or T) plus the temperature of the internal sensor as output of 4 ~ 20 mA.This second output can be used to ensure that the sensor is operating in the correct environment and prevents damage caused by overheating or over cooling. It can also be used to give approximate indications of the temperature of the air surrounding the sensor.

All PyroCouple sensors are designed with germanium lenses for precise optics. The PC21 model has a 2: 1 lens making it ideal for many applications where the sensor can be mounted near the lens. The PC151 model is designed for small or distant lenses and has an optical resolution of 15: 1. The PC301 model is designed for very small or distant lenses and has an optical resolution of 30: 1. The PCCF model is designed for such small targets with a diameter of 5mm at a distance of 100mm of the sensor.
